We established a peculiar structure of the O-specific polysaccharide (O-antigen) of a psychrotrophic strain of Acinetobacter lwoffii, EK30A, isolated from a 1.6-1.8 million-year-old Siberian permafrost subsoil sediment sample. The polysaccharide was released by mild acid degradation of the lipopolysaccharide and

The mechanism of proteolysis by serine proteases is a reasonably well-understood process. Typically, a histidine residue acting as a general base deprotonates the catalytic serine residue and the hydrolytic water molecule. We disclose here, the use of an unnatural d-amino
